I may have stalled on squats and it may be time to do my first reset.  I was well rested and fueled this morning but the bar just felt like it weighed a ton.  My last few warm ups were killer and I could tell it was going to be rough.  I doubt I could have even done 190 lb sets.  After my 3rd rep nearly didn't go up with 195 in the first set, I racked the bar and took off 10 pounds.  I struggled through 5 reps at 185 and I definitely couldn't have gotten that last rep in the last set.  Sooo... I'm not sure, I'll likely try 195 again next workout just to make sure it's a true stall and not backlash from the long weekend.  But if not, next workout I'll be dropping squats 10%, in this case 20 lbs, and start back up at 175 lbs.  Bench was probably 7.5 or 8 out of 10 exertion, and deadlift was rough.  I felt like my form sucked - too much bending at the hips - but I'm not sure.  5 pound increments moving forward on deads.  I'll be back to bodyweight on dips next time.
